How to Wire a LED Light to a Switch

A diode is an electronic semiconductor device through which current can only flow in one direction. A light emitting diode (LED) is a device that lights up when current flows through it in the proper direction. While early LEDs were low intensity and only produced red light, modern LEDs are available that release light across the visible spectrum. Because of this, they can be used for many different purposes. In order to have control over when the LED is on, you should wire it to a switch.
